I am a salaried person and am planning to buy a Flat in my HUF by availing Housing Loan. My Family & I will be staying in the flat and will pay rent to HUF for the same. My questions are as below:

2. While calculating Income from House Property, can the HUF deduct interest on home loan to arrive at Taxable income from House Property

3. Can HUF claim the principal portion as deduction under Sec 80C
